Compressed air through the wall

My concrete block foundation wall in the basement comes up one block in my attached garage. I want air in both places. Right now I only have a 4 gal double hot dog that weighs 58 lbs. It is a bit heavy for me, at my age to carry it back and forth. The compressor lives in the garage. Eventually it will be replaced with a real 5 hp, 2 stage on a 60 or 80 gal tank that will live in the basement and the air will go the other way. The distances are very short. I was thinking of using a piece of copper pipe with npt threads so I can easily re plumb in either direction. I want the pipe well anchored but I prefer not to cement it in, in case of changes in pipe size, material, etc. I thought there would be some sort of split clamp integrated with a flange that I could screw to the wall but i found nothing. The closest I found was a split hanger that hangs from threaded rod (1/4-20?). I thought of bolting it to a rt angle bracket, screwed to the wall on one or both sides of the wall. I can get clamps in any pipe size. I would use silicon sealer to keep fumes and drafts out of the basement. It is not natural gas or water so I hope code is not an issue. Anybody know of better hardware that is more purpose built for the job? Thanks.

don't overthink your install. copper pipe is a good choice, pc of black threaded pipe would work to. any type of clamp to hold it would be fine. you don't need it rock solid.even spray foam would suffice to firm it.

as far as code, that maybe a local issue that may or may not be a factor

Here is what I used when I wanted to pass air and water through the wall from my garage to my back yard.

I just drilled out a threaded adapter to make a "bushing" and ran copper through and put disconnects on each end. Now if I need air in the back yard, I just plug my hose reel into this and then I have air available in my back yard without having to run house out the side door and all the way around the house.

Thanks. That looks like an outdoor electrical plate. The right size Romex or BX Or conduit adapter with a set screw should work. I like how it covers the hole; I can use the gasket

Maybe i missed something..... just run whatever piping you are using through the wall, seal hole with what is appropriate for the situation.

If you don't want to permanently "cement" your through ******, for reasons I don't see maybe, use "Ductseal" aka Monkey ****.

Used by electricians often to seal inside conduit around wires in pipe going through walls from cold to heated locations.

Available at any Big Box, in elect dept., like $3.

Seals, but remains pliable and removable for your lifetime +.

Not sure what the post is about.

Why all the talk about like Clamping/ securing like??

Believe me, I'm a over securer of everything, but are you sending this to Mars ? Marc

The point is, there is a bunch of moving hose hanging off the pipe and some soft goop will most likely not anchor it. I either cement it in or clamp it and caulk. I am sure your putty would make good caulking. I was just looking for a good clamping suggestion.

Larry - Sorry, same time posting.

Hey, ok , if you want to secure it, silicone RTV.

You can screwdriver chisel it out in future and BFH the ****** out, if you need to replace the ******, otherwise in meantime it will both seal perfectly and secure awesomely. Marc

A picture (or 2) is worth a thousand words. So, here you go. I wanted air outside my shop as well as in.

I used a brass ****** sized long enough to get threads on both sides of the wall. Some large washers went over the ****** and then I screwed on the needed adapter to attach quick disconnects. No clamps necessary on either side. A little silicon went around the pipe to seal for air infiltration.

Found myself not bothering to drag the compressor up from the basement when working on the car. Got frustrated about having that money in the compressor and air tools, so decided to find a way to run a line through the wall.

Found this fitting in the gas fittings area at Lowes or Menards. No idea what it's called, but added some fittings to get the size right so I could set it up with quick disconnects on both ends. Just plug in and fire up the compressor in the basement, plug in the air line I keep in the garage, and good to go.

Not a setup I'd use for daily shop use, but works well for my occasional car maintenance.

Sorry about the sideways pic..

Yes that is exactly. I just used copper npt fittings that I drilled out so they would slip all the way on the tube and soldered them. I did one for air and one for water. Works great. It took me a while and everyone told me I was over thinking it as well, but it looks great.
